Filmomat Photoplug - Camera Shutter Speed Test Device

The PhotoPlug, from Filmomat, is a small light sensitive sensor which plugs into the headphone-jack of your smartphone (or iPhone headphone adapter). Together with the Shutter-Speed App (available FREE on the iOS and Android AppStore), it transforms your smartphone into a optical shutter speed tester for analog cameras.

The Plug contains a small light-sensitive element which converts light into electrical signals. All you have to to is opening the back of your camera, place it with the lens towards a bright light source, and position the PhotoPlug behind it. When you release the shutter, the light travels through the camera shutter and hits the PhotoPlug. The PhotoPlug measures the duration of that light pulse - which is equivalent to the shutter speed of your camera.

COMPACT

The PhotoPlug is only 2cm short and perfectly fits in every pocket. It doesn’t require any batteries, so you always have it on hand when you need it. This allows you to use it wherever you are, for example when buying a used camera on a flea market.

EASY TO USE

Once you have taken a measurement, the App will display the measured shutter speed of your camera. It will also calculate a deviation value in f-stops. Example: You selected 1/125sec on your camera. Your measurement tells you it is actually 1/80sec. This results in an overexposure of 2/3 f-stops!
